DISK ATTACHMENT FOR GRAIN-DRILLS.

SPECIFICATION forming part of Letters Patent No. 654,037, dated July 17,1900.

Application filed Merch Z9, 1900. Serial No. 10,590. (No model.)

To @ZZ whom t may concern:

Be it known that we, STEPHEN B. ToLsoN and ANDREW `SOHOPP, citizens ofthe United States, and residents of Belleville, in the county of St.Clair and State of Illinois, have invented certain new and usefulImprovements in Disk'Attachments for Grain-Drills, tbc. of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification.

Our invention relates to a novel manner of mounting groundsworking disksthat are used in connection with grain-drill shoes, as shown, orindependently thereof, our object being to so mount the disks as toafford for their adj ustment to any desired angle relative to thedrag-bar, while they will be rigidly held at any angle to which they maybe placed.

Our invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims. y

Figure I is a perspective view illustrative of our invention. Fig. II isa top or plan view. Fig. III is an enlarged view of the box or housingby which the disk and shoe are attached to the drag-bar. Fig. IV is Aanenlarged vertical section taken on line IV IV, Fig. II. Fig. V is anenlarged vertical section on line V V, Fig. I. Fig. VI isla horivzontalsection on line VI VI, Fig. V. Fig. VII is a detail perspective viewshowing the inner end of the arm of the shoe that is attached to thedragbar. Fig. VIII is a side elevation. Fig. IX is a section on line IXIX, Fig. VIII.

Referring to the drawings, 1 represents a drag bar, which may (with anumber of mates) be made fast to the frame of a graindrill by means of arod 2.

3 is one of the shoes of a grain-drill, made hollow, as usual, toreceive one of the feedtubes. (Not shown.) The shoe has aninwardly-extending portion 4 cast thereon, (see Fig. IV,) to which oneend of a sleeve or tube '5 is held by a bolt 6. The sleeve or tube 5forms the journal for the hub 7 of the disk 8, the hub being held fromoutward movement on the journal by a shoulder or flange 9 on 5o theouter end of the journal.

hub 7 and provided with an oil-hole 11. Between the hub and the boxthere isl an oilspace 12. The outer end of the box bears against theperiphery of the iange 9, and its inner end bears against a shoulder 13on the hub 7.

The box or housing l() is provided with an arm 14, that is pivoted tothe drag-bar by a bolt or pin 15 and having also a slot-and-boltconnection 16 with the drag-bar. The box or housing thus serves toconnect the disk to the drag-bar, and by loosening on the bolt 16 thedisk can be adjusted to any desired angle, as shown by full and dottedlines, Fig. II, and then by tightening the bolt the disk is held towhatever angle it may be adjusted. To avoid any possibility of the diskmoving from vits adjustment when at work, the shoe 3 is provided with anarm 17, that has aslot and-bolt connection 18 with the drag-bar, the

adjustment being made here at the same time as the adjustment of the arm14. There is a connection thus made between the dragbar and the disk onboth sides of the latter:- by the box 10 and its arm 14 on one side andby theshoe 3 and its arm 17 on the other side so that the disk cannotpossibly move from its adjustment.

20 represents a scraper for cleaning the disk, the arm 21 of which ismade fast to the shoe 3 by a slot-and-bolt connection 22. (See Figs. I,V, and VI.) It is important that this scraper be so arranged that it canbe efciently and quickly adjusted to the disk as it becomes worn. ThisWe accomplish by forminga concavo-convex bearing 23 between the shoeandthe arm of the scraper, as shown in Fig. V, so that when the bolt 22 isloosened and the arm moved downwardly the scraper will naturally bemoved inwardly against the disk.

The scraper cleans one side of the disk as it cornes out of the ground,and to clean the other side of the disk we form the shoe with aninturned edge 24, (see Figs. VIII and IX,) that scrapes against the diskand cleans it as it comes ont of the ground.

We claim as our inventionl. The combination of a'drag-bar, a diskpivoted to the bar, a shoe to which the disk is journaled, and an arm`on the shoe and IOO which is adjustably connected to said bar,substantially as set forth.v

2. The combination of a drag-bar, a disk, a. box inclosing the journalof the disk and provided with a lug that is pivoted to the bar and has abolt connection therewith, and a shoeto which the disk is journaled andwhich l is provided with i an arm having a slot-andbolt connection withsaid bar, substantially as set forth.

3. The combination of a drag-bar, 'a shoe having an arm adj ustablyconnected to said-i bar, a. journal connected to'said shoe,`a disk h Inpresence of"- having a hub fitting over said journal and a box inclosingsaid hub and having an` arm` that is pivoted to said bar and has also aslotand-bolt connection therewith, substantially asset forth.

4. The combination of a disk, a shoe to which the disk is journaled, anda scraper adapted to bear against the disk and having an arm that isconnected tosaid shoe by a "bolt-and-slot connection; said armhaving alconcave-convex bearin g against the shoe, substantially as and for thepurpose set forth.

In testimonywhereof We have hereunto set our hands lthis 26th day ofFebruary, 1900.
